Kas & Ros

Hosted by award winning jewellers Milena Kovanovic (Crucible London) & Ros Millar with The Ringsmiths team.  In this direct casting method, molten metal directly fills a design carved/imprinted into the surface of a cuttlebone. Producing a finished three-dimensional cast object - in this case a signet ring. This technique is one of the earliest known casting processes used by man for thousands of years.

Over the course of this 4 hour workshop we will teach you everything you need to know about how to prepare and cast your very own silver signet ring. You will have plenty of opportunity to practice and test out this variable technique which is safe, fast and versatile.

This workshop is suitable for both beginners and more advanced students. 

Each student will be provided with an apron, though we ask you to please wear suitable non- loose clothing (as you would for any other semi-messy art form). For health and safety we also recommend close toed shoes.

With a maximum of six people in any one class, there will be plenty of opportunity for one-on-one interaction with the jewellers. The workshop will take place in a hidden, heated and covered garden, housed at the back of jewellery store ‘Kas & Ros’

Make and Cast a Signet Ring

Saul

I cannot recommend this workshop enough, the teachers were great and the rings we made look amazing. I’ll be coming back to do another workshop for sure. 

Shivani 

I thoroughly enjoyed myself taking part in this class. The pace of the class was perfect, incorporating useful information about the source of cuttle fish, the science behind casting and techniques which enhances the making of such product. Milena and Ros were so patient, supportive and friendly. Snacks and beverages were also provided.  All in all, an enjoyable day which is well organised. The best part is walking away with a finished ring! 

Lucie Silveira 

Loved this class, Ros and Milena were perfect hosts as well as great teachers. I learnt how to prep a cuttle bone to create a mould for my ring, and then how to pour the molten silver, which was both scary and exciting! And then to polish and clean up the ring. Really interesting class and I love my signet ring that has a story as unique as it is. Thanks so much Ringsmiths! xxx

Lorna Searl

Milena and Ros were such great teachers! Super personable and friendly. The workshop was great and is super comfortable (especially in covid times!) I went with my boyfriend for his birthday and had a really good time. 

Highly recommend for anyone!

Ahmed  Mohideen 

Ros and Milena were very helpful in explaining everything and were very patient during the process. I have recommended the signet ring making course to many friends. Looking forward to receiving the ring back from the engraver and seeing the blue sapphire set.

Ellie

Would 100% recommend the make and cast a signet ring class to anyone! Really enjoyed learning about the background of the ring casting and getting the chance to cast the ring ourselves. Such a cute workshop and the addition of a puppy was a bonus!

Martin

I can't recommend this class enough! Excellent tuition, taking you through every step clearly and methodically, making sure everyone understood everything. Rings were sized if needed on the day prior to spending time to achieve ones desired finish. Add ones of plating and gems were very reasonable and was not pressured in any way. We can't wait to receive our finished rings complete with gems.

Amazing class to make a signet ring, so much fun, didn’t feel rushed and had the perfect amount of attention and help. Was really awesome and fun really recommend!!

James York

I went with my partner as a birthday present and I have to say it was such a good gift! It's original, thoughtful, hands on and you walk away with a very personal momentum. I came into work the next day and people absolutely lose thier minds. The rings can come up so unique. The faciliators were so nice and lovely. I instantly felt comfortable. I will 100% recommend this for anyone who might be struggling to get a personalised gift. 

Leo Petrokofsky

We had a fantastic time! Would highly recommend

Olivia Needham

Such a special and amazing experience. My husband and I had so much fun creating signet rings for a 30th birthday gift, we can’t wait to receive them and will treasure them forever! We couldn’t recommend The Ringsmiths more!

SHREA NIJJER

The class was super special! Everyone was so friendly and helpful and made the whole thing feel fun and relaxing. Thanks so much for making our bdays great :)

Hannah Roberts

Booked for my boyfriends birthday as he’d wanted a signet ring for so long but couldn’t find one he liked! The class was amazing and I highly recommend to anyone, we learnt so much, had so much fun and got some amazing rings at the end of it! Thank you so much the Ringsmiths:)

Naveen Mahil

Super fun and informative class, and loved that I was able to walk away with a new piece of sentimental jewellery! 
Would recommend as a gift idea (and already have to lots of my friends!)

Leo Vick

Really great experience. The tutors were welcoming,  supportive and friendly. I'd recommend the Signet Ring course, it was a little bit nerve-wracking to make both the mould and do the casting, but I'm really happy with the end result.

Jayd Wolfaardt

Alana Wigley

Loved the whole thing! Will be back again x

Christian Vila

I had a really great time making my rings, the staff are very welcoming and accommodating, I look forward to doing this again.

Cari Sorby

I loved my few hours at The Ringsmiths!  I made two signet rings from the casts and am so thrilled with them.  I'll be back to do another course as soon as I can.  Thank you for organising a great day.

Emma Bee

The course was informative and fun. Everyone running the course was very helpful and really loved the refreshments to keep us going on a very hot Friday afternoon. I'll cherish my ring, always and recommend this course to everyone!

Thanu Thiru

A great experience,  meeting new people and learning about jewellery making !

Piotr Majda

Amazing workshop! Attentive and helpful instructors, plenty of space for attempts to get the ring you wanted to have!

Joseph Capp

Good fun and left with a lovely unique ring!

Sophie  Nuccio

I had a wonderful day making and casting my ring!  It was more fun than anticipated!!

May Hoang

Super lovely and accommodating. I originally booked on for signet ring making and quickly realised I needed the silver ring making class for a gift I had been planning. The Ringsmiths team were so helpful and changed my booking with no hassle whatsoever. The class is simple and informative and I can't wait to receive the ring I made in the mail! 

John Bailey

What a great experience, the class was fun, we all learned some new skills and each came away with a unique piece of jewellery.  My wife is having a small gem set in her ring to finish it off. The team ensured that we were all safe handling molten metal but kept it fun all through. . A good way to celebrate our anniversary. 

Carolina de Barba

This was such an amazing experience! It’s a small group, so you get full attention and support from the whole team. They are all extremely knowledgeable and fun, ready to help when it’s time to use more complicated tools but also extremely encouraging when it comes to let your imagination fly high :) I loved it so much I’m already planning to do the different workshops they offer.

Mary Hurlock-Risdon

This is my third class and it was another fantastic one at The Ringsmiths - Ras and the team are amazing teachers, you learn real techniques, and the two signet rings I created will be long treasured.  Can't wait to take another class.  MUCH recommended.

Carissa Moore

I'm a Jeweler visiting from New York and took a Signet casting class on my last day in London. So much fun, easy to understand and the jewelry instructors were extremely patient and easy to talk to.  Very relaxing space and it was nice talking with other people taking the class. Would  recommend to anyone regardless of skill level. Plus, you get to walk away with a souvenir and memory that will last a lifetime :)

Hanna Solman 

I had the best time in this workshop!! It was hands on and informative, the space was really cute and the jewellers/instructors were so lovely and welcoming!! Could not recommend enough xx

Charlotte Lude

We recently took part in the signet ring-making workshop to celebrate my sister-in-law’s 40th birthday, and we couldn’t have chosen a better experience! Milena, Juliette, and Annabelle were fantastic guides, patiently walking us through each step of the casting process. They gave clear instructions and allowed us to create two casts, which made the experience even more enjoyable by giving us room for trial and error. The team’s fun and relaxed energy put us at ease, and I especially loved choosing from the beautiful selection of gemstones. This workshop is a perfect gift: combining a unique, hands-on experience with the added bonus of walking away with a truly special keepsake. I would definitely do this again!

Jasneek Dhillon

This was my second time attending the workshop, with my first ring made in the wax carving class. I wear that ring every day, so I wanted to try something different this time, and I’m so glad I did! It was fascinating to learn about the process and hand-design my own ring, from choosing the shape, to selecting the stone, and deciding on the finishing touches. The ladies who run the class are so welcoming and friendly, and even though I attended alone, it was a lovely group of people to spend the day with. They are there to help and guide you every step of the way, offering excellent advice. I’m really happy with my final product! Special thanks to Juliet and Ros! 

Luiza Jordan

The signet ring workshop was our second time to the Ringsmiths (we have done the silver ring one too), and it did not disappoint! Once again, the team are so patient, attentive and knowledgeable and it is always a pleasure to spend the afternoon with learning and laughing. Planning on coming back again for a third time to make our wedding bands for our big day next year. Love this place!

Rowena Bell

the signet ring making class was so much fun, you’re left alone to really make it but with just the right amount of guidance. Would really recommend this to anyone. The ladies who ran the course were amazing too! 

Mrs Sarah Jane Cuffy

I really enjoyed making a signet ring, it was a bit harder than I expected but we were given a few attempts to get it right. The people running the workshop were lovely, funny and helpful. I enjoyed it so much I'll probably go back to make another ring. 

Join us for this hands on workshop where you'll make a silver signet ring using the ancient process of cuttlebone casting.
